[syssi]

Thanks for your feedback! I will extend the docs.

@iovcharyk Please use protocol version JK02_32S and avoid the auto-detection of the new (JK02_32S) frames because it's unstable.

Hi @syssi, thanks, now I'm using protocol version JK02_32S But in order to compile it I have to use framework: type: arduino instead of "esp-idf"
